To all it may v Beifknown that I, EDWARD H. Huma- MIN,- a' citizen of the United States, residin at Oakland, in the countygof Alameda and State of California, hay einvented new and useful limprdvements in:- Air-Purifiers for Carburete'rs, of whichzthe following is a specification.

Thisinvention relates to a device for cleansing the air which is introduced into carbureters, m the use of internal combustion engines for pleasure vehicles, and particularly for road work, harvesting, etc. The carbureters rapidly become clogged by reason of the dirt which is const'antl drawn in filling the carbureter up, and additionally a good deal of the air carries fine dust into the cylinders which scores and wears them so that they ueed boring out and new pis ton rings.

a The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and .Fig. 2

claimed, having reference to-the accompany ing drawings, in-which-- A Figure 1 is an outside view of the casing. is a vertical section of the device. 15;; 3 is a plan view of the apparatus.

in the present device, the outer casing A is made with peripheral openings, as atv 2,. which-maybe five or six in number. Within this casing is fitted a perforated or screened basket 3 and inside of this is another similar one 4.- The outer chamber A I is supplied with water from a sealed source by gravity through a pipe, as shown at 5. The end of this pipe dipping into the water I 'in the chamber A will maintain the supply and whenever the water falls below that level, air will be admitted through the pipe 5 to the closed supply chamber and allow a little more water to con in and maintain the level. The space below and around'the chamber 4 and between it and'the exterior- J chamber 3 isfilled with sponge or. other porous materialthrough which air will freely draw. which sponge dipping into the water will by capillary attraction absorb enough/to 'itipartially full of water. The dust, laden ah drawn in through tlie openings in the "outer casing A and through the passa es in the part 3 will also pass through the sponge or similar material and will thus arrest the'du'st and prevent it from going into the carhureter. The air thus cleansed will be-drawn through this apparaaIn-Punrrm'n FOB- cannumsns Qpecmeatlon o! Lettert Patent.

: tu s and the opening 6:t0 the carbureterwith which it is connected; by the reciprocation of the engine pistons. -f -m .Thecasing A has a flange 7 ,at fthe-top, 8

corresponding. with a similar flange of-the .fixed head portion, through which the "air f ultimately passes to the carbureter; a bolted 1- connects these flanges in suchmanner that the casing may swing around the-bolt in a 5,- horizontal plane and expose its open upper side and t 0 interiorbaskets and spon filling which can thus be easily remov v cleaned and replaced without disturbing any j fixed part of the apparatus. Onthe' side opposite to the hinge bolts 8 is a stop andj 1 locking device, as at 9, which'serves to re tain the parts in proper operative relation,"- when closed,

Having thus described my invention, whit.

f I claim and desire to secure by Letters Pa t cut is: v

1. In an apparatus of the'cha'racterflescribed, a casing having air inlet openings :2 in its sides and a closed bottom, an inl t for water, annular interior flanges .of less diameter than the interior of the 'ca'singf'a perforated screen chamber supportedfby the flanges, a-second smaller concentrie'screen chamber located within the first inamedeaav chamber, and anintermediate porous spongy filling, the lower part of which-dips into the water, the upper part of the casing have ing an air discharge opening.

2. A carbureter filter comprising concenfllab tricforaminous baskets Jvith su porting flanges lt'tlle top and an interpose sporrfiyg absorbent filling, a casing with inwa y: projectin flanges by which the baskets-am, supported out of contact with each -0the1 and with the casing, said casing having a discharge Opening at the top and air inlet" openings around the sides, and a water sup ply for'the spongy filling. f -g 3.
